Direct answer
To change accountant, choose the new accountant first, confirm scope and fees, then authorise handover so records and professional clearance can be handled properly.
What this means in practice
- Check notice terms and outstanding fees.
- Tell the new accountant about deadlines before they quote.
- Ask what records they need from you directly.
The best next step is usually to gather the facts before asking for advice: income, expenses, dates, software, previous returns and any HMRC letters. That gives an accountant something concrete to review.
What to prepare before speaking to an accountant
- Reason for switching.
- Current engagement letter and notice terms.
- Upcoming filing deadlines.
- Software access and backups.
- Outstanding fees or unresolved work.
Examples of how the answer can change
Switching is usually straightforward when records are tidy, fees are settled and no major deadline is close.
A switch needs more planning when the previous accountant holds key records, software access is unclear, deadlines are near or work is unfinished.
The useful pattern is to separate facts from judgement. Facts are things like dates, turnover, software, invoices, bank statements, ownership and deadlines. Judgement is where a rule has to be applied to those facts. The more judgement involved, the more valuable a focused accountant conversation becomes.
How to use this guide before you speak to anyone
Prepare your engagement letter, filing deadlines, software login position, last accounts, tax returns, payroll details and reason for switching.
Then write down the decision you are trying to make in one sentence. For example, you might be trying to decide whether to file yourself, change software, register for VAT, switch accountant or clean up records before a deadline. A clear question helps an accountant respond more usefully and helps you compare answers from different providers.
Do not treat the first call as only a price check. Use it to test whether the accountant understands the situation, can explain the next step in plain English and can tell you what information they need before giving a firm view.
How to compare your options
It usually helps to compare three routes: doing it yourself, using software or bookkeeping support, and speaking to an accountant. The right route depends on the risk of getting it wrong, how much time you have, whether deadlines are close and whether the answer affects future tax or compliance.
DIY can be sensible when records are tidy, the rules are easy to check and the financial impact is modest. Software can help when the main issue is organisation, recurring transactions or digital records. Accountant support becomes more useful when interpretation, judgement, deadlines or business structure are involved.
When comparing accountants, ask for the scope in writing. A good comparison should tell you what is included, what is excluded, who will do the work, how quickly they respond, what records they need and whether they understand your business type.
A quick quality check before you decide
- Can you explain the issue in one sentence
- Do you have evidence for the figures or records involved
- Have you checked the official guidance linked on this page
- Would a mistake create penalties, extra tax, missed deadlines or messy records next year
- Do you know what you want an accountant to answer
If several of those answers are unclear, the next step is not necessarily a long engagement. It may simply be a short accountant conversation to confirm the right route and avoid building the rest of the year on a weak assumption.
What this guide is focusing on
Use this guide if you are deciding whether to pay for accountant support and trying to compare scope, risk and confidence rather than just price. For How do I change accountant, focus on how the rule meets the records, thresholds, software and decisions you actually have in front of you.
What figure, record or decision should you pin down?
Pin down what work is included, what records are tidy, how many income streams exist, deadline pressure, software quality and what judgement calls need a professional view. That gives an accountant something specific to check and stops the conversation becoming a vague discussion about tax in general.
Records to gather
- latest tax return or accounts
- income streams
- records quality
- deadline dates
- questions and scope requested
Real examples for this situation
- A simple return with tidy records may only need a light review.
- A side hustler with platform income, PAYE and VAT worries needs a more specific scope.
- A person switching accountant should prepare deadlines, authorisations and outstanding filings before asking for quotes.
A common mistake is comparing accountants only on headline fee without checking scope and responsiveness. The safest pattern is to write down the figure, source, date and evidence before deciding whether DIY, software or accountant support is enough.
When to speak to an accountant
Speak to the new accountant before resigning from the old one if deadlines are close, records are messy, or you need professional clearance handled carefully.
Questions to ask an accountant
- How will professional clearance work
- What records will you request
- What do you need from me directly
- Can you handle the next deadline
- How will fees work during handover
Mistakes to avoid
- Cancelling access before downloading records.
- Switching right before a deadline without warning the new accountant.
- Not checking what work is unfinished.
- Choosing only because of a cheaper quote.
Key takeaway
To change accountant, choose the new accountant first, confirm scope and fees, then authorise handover so records and professional clearance can be handled properly. If the facts are not simple, use this as a prompt for a proper accountant conversation rather than a final personal answer.
